Re: [RDD] RDCatch normalize above -1dB?

0 dbFS is more like 0 degrees Kelvin. 0 Kelvin is as cold as it is possible to go, and 0 dbFS is as high as it is possible to go. Rob -- Я там, где ребята толковые, Я там, где плакаты "Вперёд", Где песни рабочие новые Страна трудовая поёт. On Fri, 11 Nov 2016, al davis wrote: On Wed, 9 N

That makes sense, Bill. I disregarded the Full Scale. The program in question is Democracy Now, and we have to boost the volume every day. We also insert underwriting messages in the two breaks of the show, so it can run unattended, but that’s done in an audio editor on a Mac. When I look at the

Simon, 0 dB in Rivendell is 0 dBFS (Full Scale) the highest value that can be represented digitally. 0 dBFS is +18 dBVU (or +20 if you're SMTPE). So the default normalization Rivendell uses (-13 dBFS) is already +5 dBVU. To go to +3 dBFS you need to make a 16 bit AtoD converter take 17 bits. 😀

2016-11-08 Thread Tom Van Gorkom
I believe this is the digital scale where 0dB is absolute max before distortion so you would not want it at that level. I wonder if it has audio spikes that cause the average level to be much lower. As I understand it, normalization limits all the audio to the peaks to whatever level you set it to

[RDD] RDCatch normalize above -1dB?

2016-11-08 Thread Simon Frech
We download a program that’s always lower volume than it should be. The most I can normalize in RDCatch is -1. Is there any way to set that to something like +3 dB? Simon ___ Rivendell-dev mailing list Rivendell-dev@lists.rivendellaudio.org http://cas
